Onepostly

Onepostly is a social media API for developers, product teams and AI agents. One integration publishes, schedules and measures content across nine platforms.

Send one request with text, media URLs and destination account IDs. Onepostly handles each platform's OAuth, app registration, token refresh and rate limits, then fans the post out to the official APIs.

Features

• Publishing with text, images, video, carousels and first comments
• Scheduling with timezone support, cancellable before publish
• Normalized analytics: likes, comments and shares in one JSON shape
• Comments, DMs and engagement actions on the same accounts
• Webhooks for publish, fail, comment and DM events
• Official TypeScript and Python SDKs, plus plain REST
• MCP server so Claude Code and Cursor can create and schedule posts
• White-label OAuth consent screens

Who it's for

Developers replacing per-platform integrations, AI agent builders wiring social into agent workflows, and agencies managing many accounts from one key.
